The SNMP Management Framework presently consists of five major components:
SNMP管理框架目前由五个主要组件组成：
o An overall architecture, described in RFC 2571 [1].
o RFC 2571[1]中描述的总体架构。
o Mechanisms for describing and naming objects and events for the purpose of management. The first version of this Structure of Management Information (SMI) is called SMIv1 and described in STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The second version, called SMIv2, is described in STD 58, RFC 2578 [5], STD 58, RFC 2579 [6] and STD 58, RFC 2580 [7].
o 为管理目的描述和命名对象和事件的机制。这种管理信息结构（SMI）的第一个版本称为SMIv1，并在STD 16、RFC 1155[2]、STD 16、RFC 1212[3]和RFC 1215[4]中进行了描述。第二个版本称为SMIv2，在STD 58、RFC 2578[5]、STD 58、RFC 2579[6]和STD 58、RFC 2580[7]中进行了描述。
o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in STD 15, RFC 1157 [8]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [9] and RFC 1906 [10]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [10], RFC 2572 [11] and RFC 2574 [12].
o 用于传输管理信息的消息协议。SNMP消息协议的第一个版本称为SNMPv1，在STD 15、RFC 1157[8]中进行了描述。SNMP消息协议的第二个版本不是互联网标准跟踪协议，称为SNMPv2c，在RFC 1901[9]和RFC 1906[10]中进行了描述。消息协议的第三个版本称为SNMPv3，在RFC 1906[10]、RFC 2572[11]和RFC 2574[12]中进行了描述。
o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in STD 15, RFC 1157 [8]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [13].
o 访问管理信息的协议操作。STD 15、RFC 1157[8]中描述了第一组协议操作和相关PDU格式。RFC 1905[13]中描述了第二组协议操作和相关PDU格式。
o A set of fundamental applications described in RFC 2573 [14] and the view-based access control mechanism described in RFC 2575 [15].
o RFC 2573[14]中描述的一组基本应用程序和RFC 2575[15]中描述的基于视图的访问控制机制。
A more detailed introduction to the current SNMP Management Framework can be found in RFC 2570 [16].
有关当前SNMP管理框架的更详细介绍，请参见RFC 2570[16]。
Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI.
托管对象通过虚拟信息存储（称为管理信息库或MIB）进行访问。MIB中的对象是使用SMI中定义的机制定义的。
This memo specifies a MIB module that is compliant to the SMIv2. A MIB conforming to the SMIv1 can be produced through the appropriate translations. The resulting translated MIB must be semantically equivalent, except where objects or events are omitted because no translation is possible (use of Counter64). Some machine readable information in SMIv2 will be converted into textual descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the MIB.
此备忘录指定了符合SMIv2的MIB模块。通过适当的翻译，可以生成符合SMIv1的MIB。生成的已翻译MIB必须在语义上等效，除非由于无法翻译而省略了对象或事件（使用计数器64）。在翻译过程中，SMIv2中的一些机器可读信息将转换为SMIv1中的文本描述。但是，这种机器可读信息的丢失不被认为会改变MIB的语义。
The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, NOT RECOMMENDED, MAY, and OPTIONAL, when they appear in this document, are to be interpreted as described in RFC 2119 [23].
本文件中出现的关键词必须、不得、必需、应、不应、应、不应、推荐、不推荐、可和可选时，应按照RFC 2119[23]中所述进行解释。
This document defines a Management Information Base (MIB) for monitoring and controlling a service interworking function (IWF) for Permanent Virtual Connections (PVC) between Frame Relay and Asynchronous Transfer Mode (ATM) technologies. The agreements on which this MIB is based were reached jointly by the Frame Relay Forum and the ATM Forum and are documented in the Frame Relay Forum Document FRF.8 [17].
本文档定义了一个管理信息库（MIB），用于监控帧中继和异步传输模式（ATM）技术之间永久虚拟连接（PVC）的服务互通功能（IWF）。此MIB所依据的协议由帧中继论坛和ATM论坛共同达成，并记录在帧中继论坛文件FRF.8[17]中。
Frame relay to ATM interworking is a function that exchanges Protocol Data Units (PDU) between a frame relay service user and an ATM service user. Two types of interworking functions are specified for frame relay and ATM permanent virtual connection (PVC) service users: network interworking and service interworking.
帧中继到ATM互通是在帧中继服务用户和ATM服务用户之间交换协议数据单元（PDU）的功能。为帧中继和ATM永久虚拟连接（PVC）服务用户指定了两种类型的互通功能：网络互通和服务互通。
Network interworking provides PDU forwarding between frame relay service users inter-connected by an ATM service. Both endpoints are frame relay PVCs. Frame Relay to ATM PVC Network Interworking is defined in [20].
网络互通提供由ATM服务互连的帧中继服务用户之间的PDU转发。两个端点都是帧中继PVC。ATM PVC网络互通的帧中继定义见[20]。
Service interworking provides PDU forwarding so that the ATM service user performs no frame relaying service-specific functions and the frame relay service user performs no ATM service-specific functions. Optionally, the service IWF translates particular higher layer protocols to satisfy the requirements of end-systems. Frame Relay to ATM PVC Service Interworking is defined in [17].
服务互通提供PDU转发，以便ATM服务用户不执行帧中继服务特定功能，而帧中继服务用户不执行ATM服务特定功能。可选地，服务IWF转换特定的高层协议以满足终端系统的需求。帧中继到ATM PVC业务互通的定义见[17]。
This MIB describes management objects used to provision, monitor, and control a Frame Relay/ATM PVC Service IWF.
此MIB描述用于提供、监视和控制帧中继/ATM PVC服务IWF的管理对象。
FRF.8 [17] does not address point-to-multipoint applications of the IWF. Implementations MAY provide support for point-to-multipoint capability using this MIB.
FRF.8[17]未涉及IWF的点对多点应用。实现可以使用此MIB提供对点对多点功能的支持。
Consult FRF.8 [17] for more details on the operation of a Frame Relay/ATM PVC Service IWF.
有关帧中继/ATM PVC服务IWF操作的更多详细信息，请参考FRF.8[17]。
The Frame Relay/ATM PVC Service IWF managed objects are organized as follows:
帧中继/ATM PVC服务IWF管理对象的组织如下：
(1) FR/ATM PVC Service IWF cross-connect table,
(1) FR/ATM PVC服务IWF交叉连接表，
(2) Connection description table, and
(2) 连接描述表，以及
(3) Notification object
(3) 通知对象
The IWF cross-connect table contains one or more rows for each inter-worked connection. Each inter-worked connection is uniquely identified by the frAtmIwfConnIndex object. In the case of point-to-point, a single row is present. In the case of point-to-multipoint, one row exists for each multipoint destination. Index objects for the ATM port, VPI, VCI, frame relay port, and frame relay DLCI distinguish the constituent rows used in a point-to-multipoint case.
IWF交叉连接表包含每个工作间连接的一行或多行。每个工作间连接由frAtmIwfConnIndex对象唯一标识。在点对点的情况下，只存在一行。在点对多点的情况下，每个多点目标存在一行。ATM端口、VPI、VCI、帧中继端口和帧中继DLCI的索引对象区分点对多点情况下使用的组成行。
Each inter-worked connection has attributes governing behavior of the IWF. These attributes describe how the IWF should transform a PDU during the forwarding process and provide rules for:
每个工作间连接都具有控制IWF行为的属性。这些属性描述了IWF在转发过程中应如何转换PDU，并提供以下规则：
(1) Mapping the ATM CLP bit to frame relay DE bit
(1) 将ATM CLP位映射到帧中继DE位
(2) Mapping the ATM congestion notification bit to frame relay congestion bits
(2) 将ATM拥塞通知位映射到帧中继拥塞位
(3) Mapping higher protocol encapsulations between ATM and frame relay
(3) ATM和帧中继之间的高级协议封装映射
(4) Performing fragmentation and reassembly
(4) 执行碎片和重新组装
(5) Performing ARP translation between ATM and frame relay
(5) 在ATM和帧中继之间执行ARP转换
Typically, most connections share the same attributes. The attributes are represented in this MIB by the connection description table. Each row of the connection description table contains the attribute settings common to one or more inter-worked connections. One example would be full mapping and translation. All cross-connect table entries that require full mapping and translation services set the frAtmIwfConnectionDescriptor object to the index value for the connection description table row that contains objects set to values that provide full mapping and translation services.
通常，大多数连接共享相同的属性。属性在此MIB中由连接描述表表示。连接描述表的每一行都包含一个或多个互连连接的公共属性设置。一个例子是完整的映射和转换。所有需要完全映射和转换服务的交叉连接表项都会将FRAMIWFConnectionDescriptor对象设置为连接描述表行的索引值，该表行包含设置为提供完全映射和转换服务的值的对象。
A notification object provides cross-connect status change alerts.
通知对象提供交叉连接状态更改警报。
The Frame Relay/ATM PVC Service IWF MIB describes the cross-connections between frame relay and ATM service users. Each PVC endpoint is provisioned and managed with a technology-specific MIB as described below.
帧中继/ATM PVC服务IWF MIB描述了帧中继和ATM服务用户之间的交叉连接。每个PVC端点都使用特定于技术的MIB进行配置和管理，如下所述。
Each technology-specific MIB has a table of PVC endpoints (indexed by ifIndex and logical link address such as the DLCI or VPI/VCI). In the absence of interworking, two endpoints are cross-connected via a technology-specific cross connect table (e.g., the atmVcCrossConnectTable in the ATM MIB). However, a connection between a frame relay endpoint and an ATM endpoint requires a cross-connect in the ATM IWF MIB.
每个特定于技术的MIB都有一个PVC端点表（通过ifIndex和逻辑链接地址（如DLCI或VPI/VCI）进行索引）。在没有互通的情况下，两个端点通过特定于技术的交叉连接表（例如，ATM MIB中的atmVcCrossConnectTable）交叉连接。但是，帧中继端点和ATM端点之间的连接需要ATM IWF MIB中的交叉连接。
The following sections describe the relationship between the technology-specific MIBs and the FR/ATM PVC Service IWF MIB.
以下各节描述了特定于技术的MIB与FR/ATM PVC服务IWF MIB之间的关系。
Frame relay PVC endpoints are provisioned as rows in the Frame Relay Services MIB [19] endpoint table.
帧中继PVC端点设置为帧中继服务MIB[19]端点表中的行。
Each frame relay PVC endpoint is described in the frPVCEndptTable. A connection between two frame relay endpoints is described by an entry in the frame relay PVC cross-connect table frPVCConnectTable. The frPVCEndptConnectIdentifier object of each endpoint points to the frPVCConnectTable cross-connect table row for the connection.
frPVCEndptTable中描述了每个帧中继PVC端点。两个帧中继端点之间的连接由帧中继PVC交叉连接表frPVCConnectTable中的条目描述。每个端点的frPVCEndptConnectIdentifier对象指向连接的frPVCConnectTable交叉连接表行。
In the case of an inter-worked connection, the frPVCEndptConnectIdentifier object is set to zero. Instead, the frPVCEndptAtmIwfConnIndex object is set to the index of the FR/ATM IWF cross-connect table row.
对于工作间连接，frPVCEndptConnectIdentifier对象设置为零。相反，FRPVCENDPTATMIWFCONNDINDEX对象设置为FR/ATM IWF交叉连接表行的索引。
The frame relay PVC cross-connect table (frPVCConnectTable) does not contain an entry for the FR/ATM inter-worked connection.
帧中继PVC交叉连接表（frPVCConnectTable）不包含FR/ATM互连连接的条目。
Note that the frPVCEndptConnectIdentifier and frPVCEndptAtmIwfConnIndex objects are set by the system as a side-effect of cross-connect establishment. Consequently, these objects are read-only.
请注意，系统将frPVCEndptConnectIdentifier和FRPVCENDPTTATMIWFCONNDINDEX对象设置为交叉连接建立的副作用。因此，这些对象是只读的。
The Frame Relay DTE MIB described in [24] has no relevance to the FR/ATM PVC Service IWF MIB.
[24]中描述的帧中继DTE MIB与FR/ATM PVC服务IWF MIB无关。
ATM PVC endpoints are provisioned as rows in the ATM MIB [21] virtual connection link table.
ATM PVC端点在ATM MIB[21]虚拟连接链路表中设置为行。
Each ATM connection endpoint is described in the atmVclTable. A connection between two ATM endpoints is described by an entry in the ATM VCL cross-connect table atmVcCrossConnectTable. The atmVclCrossConnectIdentifier object of each endpoint points to the atmVcCrossConnectTable row for the connection.
ATMVCL表中描述了每个ATM连接端点。两个ATM端点之间的连接由ATM VCL交叉连接表atmVcCrossConnectTable中的条目描述。每个端点的ATMVCLCrossConnectionIdentifier对象指向连接的atmVcCrossConnectTable行。
In the case of an inter-worked connection, the atmVclCrossConnectIdentifier object is set to zero. Instead, the frAtmIwfVclCrossConnectIdentifier object in the frAtmIwfVclEntry is set to the index of the applicable FR/ATM IWF cross-connect table row.
在工作间连接的情况下，ATMVCLCrossConnectionIdentifier对象设置为零。相反，frAtmIwfVclEntry中的fratmiwfvclcrossConnectionIdentifier对象被设置为适用的FR/ATM IWF交叉连接表行的索引。
Note that the frAtmIwfVclCrossConnectIdentifier object is defined not in the ATM MIB but in Section 5 of this MIB. Specifically, the object is defined as a column object in a table that AUGMENTs the ATM MIB VCL table.
请注意，FRAMIWFVCLCrossConnectionIdentifier对象不是在ATM MIB中定义的，而是在该MIB的第5节中定义的。具体而言，该对象定义为表中的列对象，该表扩充了ATM MIB VCL表。
The ATM VCL cross-connect table (atmVcCrossConnectTable) does not contain an entry for the inter-worked connection.
ATM VCL交叉连接表（atmVcCrossConnectTable）不包含工作间连接的条目。
Note that the atmVclCrossConnectIdentifier and frAtmIwfVclCrossConnectIdentifier objects are set by the system as a side-effect of cross-connect establishment. Consequently, these objects are read-only.
请注意，系统将ATMVCLCrossConnectionIdentifier和FRAMIWFVCLCrossConnectionIdentifier对象设置为交叉连接建立的副作用。因此，这些对象是只读的。
The ifIndex defined in the IF MIB [22] identifies the specific frame relay and ATM endpoint interfaces. The values frAtmIwfConnAtmPort and frAtmIwfConnFrPort are used in this MIB as components in the index list for the frAtmIwfConnectionTable rows.
IF MIB[22]中定义的ifIndex标识特定的帧中继和ATM端点接口。值FRAMIWFCONNATMPORT和FRAMIWFCONNFRPORT在此MIB中用作FRAMIWFCONNECTONTABLE行的索引列表中的组件。
This MIB supports IWF implementations providing point-to-multipoint functionality. All rows of the cross-connect table indexed by the same frAtmIwfConnIndex MUST utilize the same frAtmIwfConnectionDescriptor value.
此MIB支持提供点对多点功能的IWF实现。由相同FRAMIWFCONNDINDEX索引的交叉连接表的所有行必须使用相同的FRAMIWFCONNECTIONDESCRIPTOR值。
A group of cross-connect table entries indexed by the same frAtmIwfConnIndex value MUST agree on which service the multipoint operation is offered. Two cases are possible:
由同一FRAMIWFCONNDEX值索引的一组交叉连接表项必须就提供多点操作的服务达成一致。可能有两种情况：
(1) Many frame relay PVCs cross-connected to one ATM PVC, or
(1) 多个帧中继PVC交叉连接到一个ATM PVC，或
(2) One frame relay PVC cross-connected to many ATM PVCs
(2) 一个帧中继PVC交叉连接到多个ATM PVC
Multiple steps are required to create a frame relay to ATM cross-connection. First, rows must be created in the following tables:
创建帧中继到ATM交叉连接需要多个步骤。首先，必须在下表中创建行：
(1) The Frame Relay Service MIB frPVCEndptTable
(1) 帧中继服务MIB frPVCEndptTable
(2) The ATM MIB atmVclTable
(2) ATM MIB atmVclTable
(3) The FR/ATM Service IWF MIB frAtmIwfConnectionDescriptorTable
(3) The FR/ATM Service IWF MIB frAtmIwfConnectionDescriptorTable
(4) The FR/ATM Service IWF MIB frAtmIwfConnectionTable
(4) FR/ATM服务IWF MIB FRAMIWFCONNECTONTABLE
Second, the newly created rows are cross-linked.
其次，新创建的行是交叉链接的。
Finally, the administrative and operational status objects are set to 'up(1)'.
最后，管理和操作状态对象设置为“up（1）”。
A step-by-step example is provided to illustrate the creation process. In this example, the term "Manager" refers to a network management system that issues SNMP protocol actions to an "Agent". The agent is integrated with the system that implements the frame relay to ATM service IWF. In this example, the following cross-connection is created:
提供了一个分步示例来说明创建过程。在此示例中，术语“管理器”指向“代理”发出SNMP协议操作的网络管理系统。该代理与实现帧中继到ATM服务IWF的系统集成。在此示例中，将创建以下交叉连接：

Step 3 - Create the FR/ATM connection descriptor
步骤3-创建FR/ATM连接描述符
a) If an existing connection descriptor is appropriate for the new connection, go to Step 4 using the selected connection descriptor index value L
a) 如果现有连接描述符适用于新连接，请使用所选连接描述符索引值L转到步骤4
b) Manager requests a new connection descriptor index value by reading frAtmIwfConnectionDescriptorIndexNext from the agent
b) Manager通过从代理读取FRAMIWFConnectionDescriptorIndexNext请求一个新的连接描述符索引值
c) Agent receives GET request for frAtmIwfConnectionDescriptorIndexNext and responds with the next available value L
c) 代理接收FRAMIwfConnectionDescriptorIndexNext的GET请求，并使用下一个可用值L进行响应
d) Manager requests a new connection descriptor row entry using the value L as the index
d) Manager使用值L作为索引请求新的连接描述符行条目
e) Agent receives SET request to create the frAtmIwfConnectionDescriptorTable row entry causes the system to create a row in the table.
e) 代理收到创建FRAMIWFConnectionDescriptorTable行条目的SET请求，导致系统在表中创建一行。
Step 4 - Create the FR/ATM cross-connect

Step 6 - Manager signals activation by issuing a SET for the frAtmIwfConnAdminStatus object using the value of 'up(1)'
步骤6-管理器通过使用“up（1）”值为frAtmIwfConnAdminStatus对象发出一个集合来发出激活信号
Step 7 - Agent receives SET request for frAtmIwfConnAdminStatus and executes internal system mechanisms to activate each PVC segment and the IWF cross-connect. The successful activation permits the agent to respond with 'up(1)' when a GET request is received for the following fields:
步骤7-代理接收frAtmIwfConnAdminStatus的设置请求，并执行内部系统机制以激活每个PVC段和IWF交叉连接。当收到以下字段的GET请求时，成功激活允许代理响应“up（1）”：
- frAtmIwfConnAtm2FrOperStatus
- 弗拉特米夫康纳特兄弟会
- frAtmIwfConnFr2AtmOperStatus
- FRAMIWFCONNFR2操作状态
- atmVclOperStatus (Note: there is no comparable FRS MIB object)
- atmVclOperStatus（注：没有可比的FRS MIB对象）
Destruction of the frame relay to ATM cross-connection is initiated by the network management system. The agent's processing of the request stimulates implementation-specific system clean-up actions. Following removal of the row in the cross-connection table, the frAtmIwfVclCrossConnectIdentifier in the frAtmIwfVclTable (AUGMENT of
帧中继到ATM交叉连接的破坏由网络管理系统发起。代理对请求的处理刺激了特定于实现的系统清理操作。删除交叉连接表中的行后，FRAMIWFVCLTTable中的FRAMIWFVCLCrossConnectionIdentifier（增加
the ATM MIB endpoint table) and frPVCEndptAtmIwfConnIndex in the Frame Relay Service MIB endpoint table are both re-initialized to zero.
帧中继服务MIB端点表中的ATM MIB端点表）和FRPVCENDPTATMIWFCONNDINDEX都重新初始化为零。
A step-by-step example is provided to illustrate the destruction process.
提供了一个分步示例来说明销毁过程。
Step 1 - Manager requests destruction of an existing row in the frAtmIwfConnectionTable by setting frAtmIwfConnRowStatus to destroy(6)
步骤1-管理器通过将frAtmIwfConnRowStatus设置为destroy（6），请求销毁frAtmIwfConnectionTable中的现有行
Step 2 - Agent receives the SET request and performs implementation-specific system clean-up actions for the cross-connection row
步骤2-代理接收SET请求并对交叉连接行执行特定于实现的系统清理操作
Step 3 - System updates the relevant cross connect information for the frame relay PVC endpoint by setting frPVCEndptAtmIwfConnIndex to 0
步骤3-系统通过将FRPVCENDPTATMIWFCONNDINDEX设置为0来更新帧中继PVC端点的相关交叉连接信息
Step 4 - System updates the relevant cross connect information for the ATM PVC endpoint as follows:
步骤4-系统更新ATM PVC端点的相关交叉连接信息，如下所示：
a) System sets frAtmIwfVclCrossConnectIdentifier to 0
a) 系统将FRAMIWFVCLCrossConnectionIdentifier设置为0
b) System sets atmVclOperStatus to 'down(2)' (Note: there is no comparable FRS MIB object)
b) 系统将atmVclOperStatus设置为“向下（2）”（注意：没有可比较的FRS MIB对象）
Following the destruction of the FR/ATM cross-connection entry, the manager MAY set the frPVCConnectRowStatus and/or atmVclRowStatus to destroy(6) the associated endpoint entries.
销毁FR/ATM交叉连接条目后，管理器可以设置frPVCConnectRowStatus和/或atmVclRowStatus来销毁（6）相关的端点条目。
At the discretion of the agent, a FR/ATM cross-connect may be reconfigured by adding and/or deleting leafs to/from the IWF topology as per the FR/ATM IWF cross-connect creation/destruction procedures. Reconfiguration of traffic/service category parameter values requires release of the FR/ATM IWF cross-connect before those parameter values may be changed for individual frame relay or ATM endpoint segments.
代理自行决定，可根据FR/ATM IWF交叉连接创建/销毁程序，通过向IWF拓扑添加和/或从IWF拓扑中删除LEAF来重新配置FR/ATM交叉连接。流量/服务类别参数值的重新配置需要释放FR/ATM IWF交叉连接，然后才能为单个帧中继或ATM端点段更改这些参数值。

A single frame relay PVC connected to a single ATM PVC is referred to as a `point-to-point' connection and is represented by a single row in the FR/ATM IWF Connection Table. The case of a single frame relay PVC connected to multiple ATM PVCs (or single ATM PVC connected to multiple frame relay PVCs) is referred to as a `point-to-multipoint' connection and is represented by multiple rows in the FR/ATM IWF Connection Table.
frAtmIwfConnectionEntry对象类型语法frAtmIwfConnectionEntry MAX-ACCESS不可访问状态当前描述“FratmiwConnectionEntry为帧中继PVC和一个或多个ATM PVC之间的互通连接，或ATM PVC和一个或多个帧中继PVC之间的互通连接提供了一个条目。连接到单个ATM PVC的单帧中继PVC被称为“点对点”连接，并由FR/ATM IWF连接表中的一行表示。单帧中继PVC连接到多个ATM PVC（或单ATM PVC连接到多帧中继PVC）的情况称为“点对多点”连接，并由FR/ATM IWF连接表中的多行表示。
The object frAtmIwfConnIndex uniquely identifies each point-to-point or point-to-multipoint connection. The manager obtains the frAtmIwfConnIndex value by reading the frAtmIwfConnIndexNext object.
对象索引唯一标识每个点对点或点对多点连接。管理器通过读取FRAMIwfConnIndexNext对象来获取FRAMIwfConnIndex值。
After a frAtmIwfConnIndex is assigned for the connection, the manager creates one or more rows in the Cross Connect Table; one for each cross-connection between the frame relay PVC and an ATM PVC. In the case of `point-to-multipoint' connections, all rows are indexed by the same frAtmIwfConnIndex value and MUST refer to the same frame relay PVC or ATM PVC respectively. An entry can be created only when at least one pair of frame relay and ATM PVCs exist.
为连接分配FRAMIWFCONNDINDEX后，管理器在交叉连接表中创建一行或多行；帧中继PVC和ATM PVC之间的每个交叉连接一个。在“点对多点”连接的情况下，所有行都由相同的FRAMIWFCONNDEX值索引，并且必须分别引用相同的帧中继PVC或ATM PVC。只有当至少存在一对帧中继和ATM PVC时，才能创建条目。
A row can be established by one-step set-request with all required parameter values and frAtmIwfConnRowStatus set to createAndGo(4). The
可以通过一步设置请求建立一行，其中包含所有必需的参数值，并将FRAMIWFCONNROWSTATUS设置为createAndGo（4）。这个
Agent should perform all error checking as needed.
A pair of cross-connected PVCs, as identified by a
particular value of the indexes, is released by

There are a number of management objects defined in this MIB that have a MAX-ACCESS clause of read-write and/or read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations.
此MIB中定义了许多管理对象，它们的MAX-ACCESS子句为read-write和/或read-create。在某些网络环境中，此类对象可能被视为敏感或易受攻击。在没有适当保护的非安全环境中支持SET操作可能会对网络操作产生负面影响。
No managed objects in this MIB contain sensitive information.
此MIB中没有包含敏感信息的托管对象。
SNMPv1 by itself is not a secure environment. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB.
SNMPv1本身不是一个安全的环境。即使网络本身是安全的（例如通过使用IPSec），即使如此，也无法控制安全网络上的谁可以访问和获取/设置（读取/更改/创建/删除）此MIB中的对象。
It is recommended that the implementers consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model RFC 2574 [12] and the View-based Access Control Model RFC 2575 [15] is recommended.
建议实施者考虑SNMPv3框架提供的安全特性。具体而言，建议使用基于用户的安全模型RFC 2574[12]和基于视图的访问控制模型RFC 2575[15]。
It is then a customer/user responsibility to ensure that the SNMP entity giving access to an instance of this MIB, is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.
然后，客户/用户有责任确保授予对此MIB实例访问权限的SNMP实体被正确配置为仅授予那些拥有确实获取或设置（更改/创建/删除）对象的合法权限的主体（用户）对对象的访问权限。
